Pastoral Care Utilization among Women Electing Pregnancy Termination for Fetal Anomalies
TL;DR: Utilization of PC is much more frequent among women undergoing prostaglandin induction of labor than D&C/D&E, and patients who experienced a previous pregnancy loss or the death of a child are also less likely to feel the need, or do not want, chaplaincy involvement.

Faint and positive amniotic fluid acetylcholinesterase with a normal sonogram
Carol L. Brown,Kelly A. Colden,Roderick F. Hume,Mark P. Johnson,Marjorie C. Treadwell,Arie Drugan,Mark I. Evans +6 more
TL;DR: Advances in ultrasonography have led to improved detection of fetal abnormalities and, with a normal karyotype, repeat invasive testing may not be necessary.
Journal ArticleDOI
Ontogeny of isolated ultrasound markers for fetal aneuploidy.
TL;DR: Transvaginal sonography at 14–16 weeks of gestation appears to provide the best time window for detection of markers for fetal abnormal karyotype, which are transient and may disappear later on in gestation.
Journal ArticleDOI
Fetoscopic versus Ultrasound-Guided Intravascular Delivery of Maternal Bone Marrow Cells in Fetal Macaques: A Technical Model for Intrauterine Haemopoietic Cell Transplantation
Citra Nurfarah Zaini Mattar,Yi-Wan Tan,Nuryanti Johana,Arijit Biswas,Lay-Geok Tan,Mahesh Choolani,Sonia Bakkour,Mark P. Johnson,Jerry Kok Yen Chan,Jerry Kok Yen Chan,Alan W. Flake +10 more
